FIG. 13 in Model-based analysis of postcranial osteology of marsupials from the Palaeocene of Itaboraí (Brazil) and the phylogenetics and biogeography of Metatheria

FIG. 13. — Details of left radii and ulnae; A-D, Caluromys; E-H, Metachirus; A, E, proximal view of radius; B, F, medial view of proximal radius; C, G, anterior view of radius and ulna; D, H, posterior view of radius and ulna. For numbered designations of specific characters see text. Prefixes before the numbers: r, radial; u, ulnar. The scales are for the proximal and distal ends, respectively. Abbreviations: HuRa, humeroradial facet; Ra, radius; RaRas, radius-radial sesamoid facet; RaScCe, radioscaphocentrale facet; RaUlp, proximal radioulnar facet; rbbrt, radial biceps brachii tuberosity; rcefo,; rcpr, radial capitular process; rdm, radial distal malleolus; rmcr, radial medial crest; Ul, ulna; UlCn, ulnocuneiform facet; ulst, ulnar styloid process. Scale bars: 2 mm.
